Definitions

  • the present invention relates to a multicast technology in the communication field, and in particular, to a method, device, and system for implementing multicast services.
  • Multicast is a method for a host to send a message to multiple specific recipients, and becomes an indispensable key technology on the new generation network.
  • IP Internet Protocol
  • a source host sends only one copy of data
  • the destination address in the data is the address of a multicast group. All recipients in the multicast group can receive the same copy of data, and only a host (destination host) in the multicast group can receive the data, and other hosts on the network cannot receive it.
  • IP addresses are categorized into four classes, namely, classes A-D. Class D addresses are reserved as multicast addresses. In IPv4, all IP addresses from 224.0.0.0 to 239.255.255.255 are class D addresses. Addresses from 224.0.0.0 to 224.0.0.255 are reserved.
  • Addresses from 224.0.1.0 to 238.255.255.255 are multicast addresses for users and are valid on the entire network. Addresses from 239.0.0.0 to 239.255.255.255 are administratively scoped multicast addresses and are valid in the specific local scope. On an IPv4 multicast network, how to use addresses other than known and reserved multicast addresses is not specified. Therefore, addresses may conflict.
  • IPTV Internet Protocol Television
  • UE User Equipment
  • EPG Electronic Program Guide
  • Multicast addresses provided by different IPTV operators may be the same, and multicast paths of most programs of one IPTV operator may also be the same. Therefore, a conflict may occur.
  • channels of each IPTV operator may be allocated different multicast addresses. If each channel requires one IP multicast address, the bearer network needs to maintain many multicast paths. Thus, the maintenance burden is very heavy.
  • the network operator allocates multicast addresses to channels of an IPTV operator and provides an EPG in a unified manner, thus ensuring that multicast addresses on the bearer network do not conflict.
  • the solution solves the possible multicast address conflict problem when multiple IPTV operators share one bearer network.
  • multicast addresses of channels of an IPTV operator are allocated by a network operator, multicast addresses of channels of the IPTV operator can hardly be consistent when the network of the IPTV operator needs to be connected to multiple bearer networks.
  • the bearer network still needs to maintain many multicast paths.
  • Document D1 ( EP1 950 907A ) describes a method for implementing multicast in the MAC in MAC network.
  • the inventive method adds into the PBB the correspondence of the multicast address between the private network and the public network as well as the multicast forwarding tables. (See abstract of the D1)
  • CE1 sends a multicast message to PBB1;
  • PBB1 replaces the private network multicast address in the received multicast message into the corresponding public network multicast address according to the above corresponding relationship (See column 10, paragraph [0071]).
  • Document D2 ( US 2005/190765A1 ) describes a multicast network unit for delivering data between independent multicast network domains.
  • the multicast network unit includes an extraction part for extracting a multicast delivery destination address from received data, a holder part for holding conversation data where the multicast delivery destination address corresponds to a delivery source address, and a judgment part for judging whether the multicast delivery destination address is held and outputting the result of a judgment (See the abstract of the document D2).
  • a multicast packet transfer system includes a first packet transfer apparatus and a second packet transfer apparatus.
  • the first packet transfer apparatus transmits transfer packet data relating to an IP header and a UDP header of a multicast packet when the multicast packet is received, rewrites a header section of the multicast packet to produce a unicast packet, and transmits the unicast packet.
  • the second packet transfer apparatus receives the transfer packet data and the unicast packet, and reproduces the multicast packet based on the received unicast packet and the received transfer packet data (See the abstract of the document D3).
  • the present invention provides a method, a device, and a system for implementing multicast services to reduce the number of multicast paths to be maintained by the bearer network.
  • the method for implementing multicast services includes:
  • the multicast address management entity includes:
  • the system for implementing multicast services includes a multicast address management entity of the second aspect and two or more data transmission devices, each of the data transmission devices comprises an external interface module (71) and an internal interface module (72), wherein the external interface module or the internal interface module is configured to exchange multicast service data with an external device and an internal device on a bearer network respectively, and further comprises:
  • the multicast address management entity is adapted to: set up a mapping between an original multicast address ID of multicast service data and a multicast address ID inside the bearer network, and send the mapping information to the data transmission device located at the ingress and the data transmission device located at the egress of a multicast path respectively.
  • the data transmission device at the ingress of the multicast path is configured to convert the original multicast address ID of the received multicast service data into the multicast address ID inside the bearer network according to the mapping, and send the multicast service data.
  • the data transmission device at the egress of the multicast path is configured to convert the multicast address ID inside the bearer network into the original multicast address ID of the multicast service data according to the mapping relationship information, and send the multicast service data.
  • an original multicast address ID of multicast service data is mapped to a multicast address ID inside the bearer network, and the multicast service data is sent to an ingress node and an egress node of a multicast path.
  • the multicast address ID inside the bearer network is used when the multicast service data is transmitted inside the bearer network and the original multicast address ID is used when the multicast service data is transmitted outside the bearer network. Therefore, internal multicast addresses of the bearer network do not conflict.
  • a proper address mapping can be used to reduce the number of multicast paths to be maintained on the bearer network.
  • the control and data processes of a UE and an IPTV operator do not change.
  • the bearer control layer and the bearer layer convert multicast addresses in control and data streams. Multicast addresses allocated by the IPTV operator are still used outside the multicast service bearer network, and internal multicast addresses of the bearer network allocated by the bearer control layer and the bearer layer are used inside the multicast service bearer network for transmitting multicast services. Thus, a conflict of multicast addresses inside the bearer network is avoided.
  • FIG. 2 is a flowchart for controlling multicast addresses in an embodiment of the present invention.
  • a UE sends multicast address information (such as a multicast address pair ⁇ G,S>, where "G" is a multicast address and "S" is a multicast source address) to a Resource and Admission Control Subsystem (RACS) at the bearer control layer through an Application Function (AF); and the RACS maps the multicast address pair to a multicast address pair ⁇ G',S'> managed by the RACS, and sends the mapping of the multicast address pair to an ingress node and an egress node of a multicast path of the multicast service.
  • the process includes the following steps:
  • the control function of the RACS at the bearer control layer is as follows: implementing admission control based on a storage policy, and accepting or rejecting a multicast service request. If the RACS accepts a multicast service request from the UE, the RACS reserves resources for transmitting the multicast service data, sets up a multicast path for transmitting the multicast streams, and maps the multicast address pair.
  • Step 204 The bearer control layer returns a response indicating the setting is complete to the service control layer.
  • Step 205 The service control layer notifies the UE of success of the multicast service request, and sends the multicast address pair ⁇ G,S> of the requested multicast service to the UE.
  • step 203 if the bearer control layer reserves resources for the multicast service requested by the UE, but does not set up a multicast path for the multicast service requested by the UE (or does not add the UE to the multicast path), after the UE receives the notification indicating success of the multicast service request sent by the service control layer in step 205, step 206 needs to be executed. That is, the UE sends a multicast joining request according to the obtained multicast address pair ⁇ G,S>, and the request carries the multicast address pair ⁇ G,S>. When the request arrives at the egress node of the multicast path, the multicast address pair ⁇ G,S> in the multicast joining request is mapped to ⁇ G',S'>. The multicast joining request is processed according to a common process.
  • multicast address information can be identified by a multicast address G.
  • multicast address G can be identified by a multicast address G.
  • mapping multicast address information provided by the IPTV operator to multicast address information managed by the bearer network operator, setting up a mapping between multicast addresses, and sending the mapping information to an ingress node and an egress node of a multicast path may be based on the multicast service request of a UE, or may be: configuring the mapping information on an ingress node and an egress node of a multicast path in static configuration mode according to the networking conditions or network planning through the RACS or directly.
  • FIG. 3 is a flowchart for transmitting multicast service streams.
  • edge nodes of the multicast service bearer network include nodes a-f.
  • the node f is the ingress node of a multicast path and the node a is the egress node of the multicast path.
  • the multicast streams with the multicast address pair ⁇ G,S> arrive at the ingress node f from a multicast source, and then enter the bearer network from the ingress node f.
  • the ingress node f converts the multicast address pair ⁇ G,S> into ⁇ G',S'> according to the multicast address mapping information.
  • the multicast streams with the multicast address pair ⁇ G',S'> are routed to the egress node a of the bearer network along the multicast path.
  • the egress node a converts the multicast address pair ⁇ G',S'> of the multicast streams into ⁇ G,S> according to the multicast address mapping information, and sends the multicast streams to the UE.
  • the ingress node f maps the ingress multicast group address ⁇ G,S> to the egress multicast group address ⁇ G',S'> according to the multicast address mapping table sent to it (in the table, the ingress multicast group is ⁇ G,S>, and the egress multicast group is ⁇ G',S'>).
  • multicast address information provided by the IPTV operator is converted into internal multicast address information of the bearer network.
  • the egress node a maps the ingress multicast group address ⁇ G',S'> into the egress multicast group address ⁇ G,S> according to the multicast address mapping table sent to it (in the table, the ingress multicast group is ⁇ G',S'>, and the egress multicast group is ⁇ G,S>).
  • the ingress multicast group is ⁇ G',S'>
  • the egress multicast group is ⁇ G,S>
  • the address information of multicast service data is still provided by the IPTV operator.
  • Multicast service data uses multicast address information provided by the bearer network when it is transmitted inside the bearer network. Therefore, when the network of the IPTV operator needs to be connected to multiple bearer networks, the multicast addresses of the multicast services of the IPTV operator can be consistent. Through address mapping, the addresses of the multicast services do not conflict inside the bearer network.
  • the address information of multicast service data is still provided by the IPTV operator. This facilitates IPTV operators to add services and facilitates menu management.

  • embodiments of the present invention provide a method for implementing multicast services.

  • a UE does not need to be authenticated and charged according to each request. Therefore, when the UE requests a multicast service package, the UE needs to request multicast groups corresponding to a group of multicast service streams in the multicast service package.
  • the multicast paths of these multicast service streams are consistent, but multicast addresses are different. If the bearer network maintains multicast paths separately according to multicast addresses, the maintenance burden is very heavy.
  • the present invention maps the multicast address pairs ⁇ G1,S1>, ⁇ G2,S2>, ⁇ G3,S3>, ..., and ⁇ Gn,Sn> of a group of multicast service streams in the same multicast service package to a group of multicast address pairs ⁇ G',S1'>, ⁇ G',S2'>, ⁇ G',S3'>, ..., and ⁇ G',Sn'> that have the same multicast address according to the networking conditions or network planning.
  • the bearer network maintains only the multicast paths of the multicast service package according to the multicast address G', and uses ⁇ G',*> to maintain and allocate resources for the internal multicast paths on the bearer network in a unified manner so that the bearer network can implement simplified control for the group of multicast service streams.
